find the excluded values of the rational expression 3 _________________ n2 - 5n + 4
excluded values of the rational expression is where n2 - 5n + 4=0 so find this 2 values of n by solving this equation
\[5n^{3} + 4n^{2} -3 = 0\] \[n(5n^{2} + 4n) = 3\] \[n = 3 or 5n^{2} + 4n -3 = 0\]
there is a 3 over the rational expression the answer can not be 0 as that is not one of the answers listed in the multiple choice
Can you say what is the multiple choice?
a). 4 and 1 b). -5 and 4 c). -4 and -1 d). 3 and -5
I think it's 3 and -5 is right
because I said n = 3 OR 5n2+4n−3=0
oh I think you changed the problem
It was n't like that
?
Did you change the problem?
No, its the same
ok wait a second I will solve it
No there is something wrong with numbers Can you make sure that you have the same problem?
Ok I didn't put this right, n2 should be n^2
sorry
I know I mean the numbers? Is it right?
Im not sure what your asking me
Can you message me?
What do you want me to message you?
Can you write the problem again please?
3 ______________ n^2 - 5n + 4
it doesn't have any solution from the multiple choice you have
by ^ i mean to the power of
I know that
and the full sentence is find the excluded values of the rational expression (then what i wrote)
Your sure theres no answer?
No wait, Now I know what you want to solve.
to find the excluded values, you have to make n2-5n+4=0 and then solve this equation (n+1)(n+4) n= -1 OR n= -4 Do you have these answers in the multiple choice?
yes i do, but can you show me how you got that answer?
I told you To find the excluded values you have to have something like 1/0 or anything undefind So to make your equation undefined, you have to set n2-5n+4=0 to make it 3/0 right? then solve the equation to find values for n (n+4)(n+1) then, n= -4 Or n= -1
Oh, ok. Thanks for your help!
No problem ur welcome Do you have any other questions?
No, thanks though.
message me if you want me solve any problem OK?
ok
